Answer:
The Cl⁻ and K⁺ are spectator ions.
Explanation:
Balanced Chemical equation:
BaCl₂(aq) + K₂CrO₄(aq) → BaCrO₄(s) + 2KCl (aq)
Ionic equation:
Ba²⁺(aq) + 2Cl⁻(aq) + 2K⁺(aq) + CrO₄²⁻(aq) → BaCrO₄(s) + 2k⁺(aq) + 2Cl⁻ (aq)
Net ionic equation:
Ba²⁺(aq) + CrO₄²⁻(aq) → BaCrO₄(s)
The Cl⁻ and K⁺ are spectator ions that's why these are not written in net ionic equation. The BaCrO₄ can not be splitted into ions because it is present in solid form.
Spectator ions:
These ions are same in both side of chemical reaction. These ions are cancel out. Their presence can not effect the equilibrium of reaction that's why these ions are omitted in net ionic equation.
Answer:
solid particles are tightly held.
liquid particles have perfectly inelastic collisions
gas move in constant random motion
vapour
False, frogs cannot see in all directions.
The magnesium sulfide having a weaker coulombic interaction would have a lower melting point. Option D
<h3>What is the correct image?</h3>
We know that a substance is said to be ionic if the substance is formed by the interaction of two ions. We know that one of the ions must be positive and the other must be negative. The magnitude of the charges would have an impact on the nature of the interaction between the charges.
Since we know that magnesium sulfide has a double negative charge on sulfur and a double positive charge on magnesium while the sodium has a single positive charge and the chloride has a single negative charge, the magnitude of the interaction between the sodium and the chloride ions is higher thus the magnesium chloride compound shown in image 1 would have a lower melting point.
